DETAILED DESCRIPTION

[0076] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0077] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0078] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0079] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0080] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0081] The production of hollow noodles mainly includes the following steps: kneading, resting, rolling, cutting, stretching, and drying. In the prior art, the equipment used for mechanical production of hollow noodles generally fixes the pressing roller on a conveyor belt, and the dough is flattened after passing through the pressing roller by the movement of the conveyor belt, and then the flattened dough is cut into strips or pieces by a cutting component. The inventor found that because the dough for preparing hollow noodles is resting, the flattened dough embryo further rests on the transmission component over time, resulting in it becoming less flat, which affects the subsequent process.

[0082] Please refer to Figure 1 To solve the above problems, this embodiment provides a flattening and cutting device 100, which can better realize the flattening and cutting process of the dough blank. Of course, the flattening and cutting device 100 can also be used in other fields, and this application does not limit its application to rolling and cutting of the dough blank.

[0083] Please refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the flattening and cutting device 100 includes a transmission component 110, a rolling component 130 and a cutting component 170. The transmission component 110 is configured to install a base and to be used for conveying. The cutting component 170 is disposed at one end of the transmission component 110, and can cut the blank carried on the transmission component 110 along the width direction of the transmission component 110. The rolling component 130 is movably mounted on the transmission component 110 so that the rolling component 130 can reciprocate in the transmission direction of the transmission component 110. When the rolling component 130 moves in a direction away from the cutting component 170, the blank on the transmission component 110 can be pressed into a sheet. When the rolling component 130 moves in a direction close to the cutting component 170, the rolling component 130 can be lifted.

[0084] In this embodiment, by setting the transmission component 110, the blank placed on the upper part can be automatically transmitted according to the processing requirements. When preparing hollow noodles, the transmission component 110 can also be used as a fermentation bed. The transmission component 110 is provided with a pressing roller 132 component and a cutting component 170, so that the rolling component 130 flattens the blank on the transmission component 110 into a sheet, and the cutting component 170 can cut the sheeted blank into a long strip according to the requirements. Secondly, when making hollow noodles, the dough embryo carried by the transmission component 110 will become uneven in thickness even after the rolling component 130 rolls. Therefore, the present application movably mounts the rolling component 130 on the transmission component 110, so that before cutting, the rolling roller 132 component can be reciprocated in the transmission direction of the transmission component 110, so that the flattened dough embryo can be further flattened, and then cut, so that the cut long strip of dough embryo can be made uniform in thickness. Furthermore, the dough embryo will be squeezed to both sides during the reciprocating rolling process of the rolling assembly 130, causing the side of the dough embryo cut by the cutting assembly 170 to be convex and uneven, which affects the shape of the long strip of dough embryo formed when the next cutting is cut. However, the present application sets the rolling assembly 130 to be liftable, so that when the rolling assembly 130 moves away from the cutting assembly 170, the rolling assembly 130 does not lift, so that the side of the dough embryo away from the cutting assembly 170 can extend outward during rolling. When the rolling assembly 130 moves toward the direction close to the cutting assembly 170, the rolling assembly 130 lifts, so that the dough embryo will not be squeezed toward one side of the cutting assembly 170, thereby ensuring that the cutting surface is flush.

[0085] In this embodiment, the transmission assembly 110 is a conveyor belt, which mainly includes a frame, a belt body, a driving device, rollers, a tensioning device and other components. A roller is provided at each end of the frame. The belt body is wound around two rollers, and the driving device is connected to one of the rollers. The operation of the driving device can drive the rollers to rotate, thereby driving the belt body to move.

[0086] In this embodiment, the rolling assembly 130 and the cutting assembly 170 are both connected to the frame of the transmission assembly 110 .

[0087] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the rolling assembly 130 includes a moving assembly 131 and a pressure roller 132. The moving assembly 131 is installed on the transmission assembly 110. Specifically, the moving assembly 131 is installed on the frame of the pressure transmission assembly 110. The pressure roller 132 is movably installed on the moving assembly 131. The moving assembly 131 can drive the pressure roller 132 to reciprocate along the transmission direction of the transmission assembly 110. When the moving assembly 131 drives the pressure roller 132 to move in a direction away from the cutting assembly 170, the pressure roller 132 can press the blank carried on the transmission assembly 110 into a sheet. When the moving assembly 131 drives the pressure roller 132 to move in a direction close to the cutting assembly 170, the pressure roller 132 can be lifted.

[0088] In this embodiment, the pressure roller 132 is lifted upward, so that the structure can be simplified.

[0089] Of course, in some other embodiments of the present application, the rolling assembly 130 can be lifted relative to the transmission assembly 110. For example, the frame of the moving assembly 131 is connected to the transmission assembly 110 through an electric, pneumatic or hydraulic cylinder or other retractable components, so that the rolling assembly 130 can be lifted as a whole. Therefore, when the pressing roller 132 moves toward the cutting assembly 170, the rolling assembly 130 is lifted as a whole and will not squeeze the dough blank. When the rolling assembly 130 moves in a direction away from the cutting assembly 170, the rolling assembly 130 can be lowered as a whole to a preset height to roll the dough blank.

[0090] In this embodiment, the moving assembly 131 includes a mounting frame 133 and a moving assembly 134. The pressure roller 132 is movably mounted on the mounting frame 133. The moving assembly 134 is arranged on the transmission assembly 110, and the mounting frame 133 is transmission-connected to the transmission assembly 110. The moving assembly 134 can drive the mounting frame 133 to reciprocate along the transmission direction of the transmission assembly 110. When the mounting frame 133 moves toward the direction close to the cutting assembly 170, the pressure roller 132 can be lifted relative to the mounting frame 133 under the action of the blank. When the mounting frame 133 moves toward the direction away from the cutting assembly 170, the mounting frame 133 can limit the movement of the pressure roller 132 so that the pressure roller 132 can press the blank into a sheet.

[0091] In this embodiment, the moving assembly 134 is mounted on the mounting frame 133, and the pressure roller 132 is movably mounted on the mounting frame 133, and the moving assembly 134 is set on the frame of the transmission assembly. The moving assembly 134 does not make a lifting movement relative to the transmission assembly 110, and only the pressure roller 132 makes a lifting movement relative to the mounting frame 133, and the structure is simple. When the mounting frame 133 moves away from the cutting assembly 170, the lifting of the pressure roller 132 can be limited by the position limiting of the pressure roller 132 by the mounting frame 133, and when moving in the reverse direction, the force direction of the pressure roller 132 changes, and the pressure roller 132 will be lifted.

[0092] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the pressure roller 132 is provided with a connecting portion 135. The connecting portion 135 is hinged to the mounting frame 133 through a rotating shaft 136. The axis of the rotating shaft 136 is parallel to and spaced from the axis of the pressure roller 132. A limiting portion 137 is provided on the mounting frame 133 on a side of the pressure roller 132 close to the cutting assembly 170. When the mounting frame 133 moves toward the direction close to the cutting assembly 170, the pressure roller 132 is lifted by rotating along the rotating shaft 136 in a direction away from the cutting assembly 170 under the action of the blank. When the mounting frame 133 moves toward the direction away from the cutting assembly 170, the pressure roller 132 abuts against the limiting portion 137, which can limit the pressure roller 132 from rotating along the rotating shaft 136 in a direction close to the cutting assembly 170.

[0093] In this embodiment, a connecting portion 135 is provided on the pressing roller 132, so that the axis of the connecting shaft of the rotational connection between the pressing roller 132 and the mounting frame 133 is spaced and misaligned with the axis of the pressing roller 132, so that the pressing roller 132 can swing along the axis of the connecting shaft according to the force. A limiting portion 137 is provided on the side of the mounting frame 133 away from the cutting assembly 170, so that when the mounting frame 133 moves in a direction away from the cutting assembly 170, the dough embryo will give the pressing roller 132 a component force in the direction of the cutting assembly 170, pushing the pressing roller 132, but due to the provision of the limiting portion 137, the pressing roller 132 is limited from rotating along the rotating shaft 136 in the direction close to the cutting assembly 170. When the mounting frame 133 moves in a direction close to the cutting assembly 170, the pressing roller 132 is subjected to a force in the direction away from the cutting assembly 170 by the dough embryo, and the limiting portion 137 is not provided in this direction, so that the pressing roller 132 will rotate along the rotating shaft 136, thereby lifting. This arrangement has a simple structure and can be realized without the need to provide electric drive components and electric control components.

[0094] In this embodiment, the pressure roller 132 includes a mounting shaft 138 and a rotating roller 139. The rotating roller 139 is rotatably mounted on the mounting shaft 138, and both ends of the mounting shaft 138 extend out of both ends of the rotating roller 139. Both ends of the mounting shaft 138 are provided with connecting portions 135 along the radial direction of the mounting shaft 138. Two connecting lugs 141 corresponding to the two connecting portions 135 are provided on the side of the mounting frame 133 away from the cutting assembly 170. The two connecting lugs 141 are hinged to the two connecting portions 135 through the rotating shaft 136 in a one-to-one correspondence. A limiting portion 137 is formed on the end surface of one side of the mounting frame 133 away from the cutting assembly 170.

[0095] Of course, in some other embodiments of the present application, the mounting shaft 138 may be connected to the mounting frame 133 by telescopic elements such as telescopic cylinders, hinges, etc., so as to realize the lifting of the rotating shaft 136 .

[0096] Secondly, please refer to Figure 6 and Figure 7 , an arcuate slot or an inclined slot may also be provided on the mounting frame 133. The mounting shaft 138 is installed in the arcuate slot or the inclined slot, so that when the pressing roller 132 is subjected to a force away from the cutting assembly 170, it can slide and rise along the arcuate slot or the inclined slot.

[0097] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the motion assembly 134 includes a fixing member 142, a first rack 143, a driving motor 144 and a slide rail assembly 145. The number of the first racks 143 includes two. The two first racks 143 are respectively installed on both sides of the length direction of the transmission assembly 110 through the fixing member 142, and the side of the first rack 143 with teeth faces the transmission assembly 110. The mounting frame 133 includes a transverse plate 148 and end plates 149 arranged on both sides of the transverse plate 148. The transverse plate 148 is installed above the two first racks 143 through the slide rail assembly 145, and can reciprocate along the length direction of the first racks 143. The two ends of the pressure roller 132 are movably connected to the end plates 149 on both sides. A transmission shaft is rotatably arranged between the two end plates 149, and the positions of the transmission shaft corresponding to the two first racks 143 are respectively provided with first gears 151 meshing with the first racks 143. The driving motor 144 is installed on the outer side of an end plate 149, and the output shaft of the driving motor 144 is connected to the transmission shaft.

[0098] In this embodiment, the first rack 143 and the driving motor 144 are provided, and the driving motor 144 is connected to the transmission shaft. The driving motor 144 is used to drive the first gear 151 to rotate, thereby driving the mounting frame 133 to reciprocate along the first rack 143, so that the structure is simple.

[0099] Please refer to Figure 3 In this embodiment, the fixing member 142 includes a plurality of first screw rods 147. The plurality of first screw rods 147 are vertically mounted on both sides of the transmission assembly 110, and the first rack 143 is mounted on the top of the first screw rods 147. The mounting height of the first rack 143 can be adjusted by the first screw rods 147 to adjust the height of the pressure roller 132.

[0100] In this embodiment, the fixing member 142 is set as the first screw rod 147, so that the installation height of the first rack 143 can be adjusted by the first screw rod 147, and then the height of the pressing roller 132 can be adjusted, so as to change the thickness of the dough blank when flattened.

[0101] Specifically, a through hole is provided on the first rack 143, and the first screw 147 is inserted into the through hole. Two nuts are provided on the first screw 147, one nut is located at the top of the first rack 143, and the other nut is located at the bottom of the first rack 143. The first rack 143 is fixed by clamping the two nuts, and the two nuts can be adjusted when adjusting the height of the first rack 143.

[0102] Of course, in some other embodiments of the present application, the fixing member 142 can also be directly provided with an electric telescopic element, so that the thickness of the pressed dough embryo can be adjusted and the pressing roller 132 can be lifted at the same time.

[0103] Please refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the cutting assembly 170 includes a supporting bracket 171, a cutting blade 172, and a driving assembly 173. The supporting bracket 171 is disposed on the transmission assembly 110 along the width direction of the transmission assembly 110. The driving assembly 173 is mounted on the supporting bracket 171, and the cutting blade 172 is transmission-connected to the driving assembly 173. The driving assembly 173 can drive the cutting blade 172 to move along the supporting bracket 171.

[0104] In this embodiment, the driving assembly 173 is installed on the supporting bracket 171, so that the driving assembly 173 can drive the cutting blade 172 to move along the supporting bracket, thereby achieving better cutting.

[0105] Please refer to Figure 1 , Figure 2 and Figure 5In this embodiment, the bearing bracket 171 includes two support members 174, four second screw rods 175, two second racks 176, a mounting plate 177, a gear shaft 178, a motor 179 and two proximity switches 181 arranged on both sides of the transmission assembly 110 in the width direction.

[0107] Secondly, the utility model also provides a hollow noodle production line, including a proofing device, a strip cutting device and the flattening and cutting device 100 of the above-mentioned embodiment. The transmission component 110 can carry and transport the dough. The rolling component 130 can flatten the dough carried by the transmission component 110. The cutting component 170 can cut the flattened dough into block-shaped dough embryos of a preset width. The proofing device can make the dough embryos proof. The strip cutting device can cut the proofed dough embryos into multiple strips.

[0108] The hollow noodle production line provided in this embodiment can conveniently realize the production of hollow noodles on the production day.

[0109] In summary, the working principle and beneficial effects of the flattening and cutting device 100 and the hollow noodle production line provided by the embodiment of the utility model are as follows:

[0110] The present application can automatically transfer the blank placed on the upper part according to the processing requirements by setting the transmission component 110. When preparing hollow noodles, the transmission component 110 can also be used as a fermentation bed. The transmission component 110 is provided with a rolling component 132 and a cutting component 170, so that the rolling component 132 flattens the blank on the transmission component 110 into a sheet, and the cutting component 170 can cut the sheeted blank into long strips according to the requirements. When making hollow noodles, the dough embryo carried by the transmission component 110 will become uneven in thickness after being rolled by the rolling component 130. Therefore, the present application movably installs the rolling component 130 on the transmission component 110, so that before cutting, the rolling component 132 can reciprocate in the transmission direction of the transmission component 110, thereby further flattening the flattened dough embryo, and then cutting, so that the cut long strips of dough embryo can be made uniform in thickness. During the reciprocating rolling process of the rolling assembly 132, the dough embryo will be squeezed to both sides, causing the side cut by the cutting assembly 170 to be convex and uneven, which affects the cutting process of the next time to form a long strip of dough embryo. However, the present application sets the rolling assembly 132 to be liftable, so that when the rolling assembly 130 moves away from the cutting assembly 170, the rolling assembly 132 does not lift, so that the side of the dough embryo away from the cutting assembly 170 can extend outward during rolling. When the rolling assembly 130 moves toward the direction close to the cutting assembly 170, the rolling assembly 130 lifts, so that the dough embryo will not be squeezed toward one side of the cutting assembly 170, thereby ensuring that the cutting surface is flush.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
